Let's face it you love your truck or muscle car and you want it to be noticed and running at its best. Flowmaster American Thunder exhaust systems are one of the best out there with a great sound and power enhancing performance.

Everyone wants their exhaust to sound great, but first things first – it has to boost your engine's performance. Flowmaster exhaust systems are going to allow your engine to more easily emit exhaust fumes by optimizing the travel from engine to tip. Reduce back-pressure and you boost power. Boost power and you go faster.

How does Flowmaster create such great sound from their exhaust kits you ask? The sound is created by a muffler that is manufactured for not just that great "Flowmaster Sound" but for optimal power and mileage. Every exhaust is perfectly designed to work the best with your ride.

The Flowmaster American Thunder exhaust systems come with an aggressive sound. Tubing is constructed out of 16-gauge stainless steel. Each truck and car exhaust system is mandrel bent for an even flow and exit. Flowmaster exhaust systems come complete with muffler, hangers, clamps and tip for easier installation.

Customize your car, truck, or SUV the way you want with application offering a single or dual exit exhaust kit. So what are you waiting for? Get yourself the Flowmaster American Thunder exhaust system today!

Everything was as expected. Installation was very easy and instructions were precise. The only thing was I had to go buy a bushing for the driver side hanger because there was a previous dual exhaust installed on my truck. Only suggestion is there could be an extra bushing for the hangers. The sound is great as well and not to much noise inside the cab. Thank you!
